1. Jonathan James

JonathonJamesKnown as “comrade” by many online, 15-year-old Jonathan James was the first juvenile convicted and jailed in the United States for hacking. James hacked into companies like Bell South, as well as the Miami-Dade school system and the Department of Defense in 1999. He gained access to information like the source code responsible for operating the International Space Station.

Once NASA detected the breach, the space agency shut down their computers for three weeks, apparently losing an estimated $41,000. Arrested on January 26, 2000, James plea-bargained and was sentenced to house arrest and probation. He later served six months in an Alabama prison after failing a drug test and thus violating his probation. Boston Market, Barnes & Noble, Office Max and other companies were victims of a 2007 massive hack. James was investigated by law enforcement for the crimes despite his denying any involvement.

James was found dead from a self-inflicted gunshot wound on May 18, 2008. In his suicide note he wrote he was troubled by the justice system and believed he would be prosecuted for newer crimes with which he had nothing to do.
